You are mistaken if you think that a dog has only one nose.
It turns out that your four-legged friend is the owner of a second similar organ.
The latter has several names at once. The following are often used: "vomeronasal organ", "vomeronasal organ".
Sometimes the name "Jacobson's organ" is also used.
The dog's second nose is located between the nostrils and the roof of the mouth.
Why does a dog need a second nose?
There is no exact answer to this question. But there is a rather interesting assumption.
According to this hypothesis, our barking four-legged friends use an unusual organ to recognize marks left by other dogs.
In other words, the second nose can be used by dogs to “analyze” detected odors.
It is possible that the vomeronasal organ allows pets to obtain information about the age, gender, and health of the dog that left the mark.
It is possible that the second nose allows dogs to obtain important information about other representatives of the fauna, as well as to learn about the presence of dangerous substances.
